METHOD OF MAKING ummmss Original application filed February 4, 1927, Serial No. 166,980. Divided and this application filed Kay 8, 1929. Serial No. 880,694.

This invention relates to the method of making umbrellas, and more particularly to the method of sewing umbrella covers to ornamental tips adapted to be mountedon the ends of the umbrella frame ribs, now so extensively used, as distinguished from the former method of sewing the umbrella cover directly to the ends of the ribs provided with the usual eye for receiving the thread.

The present application is a division of my earlier Patent 1,727,908, dated September 10, 1929, covering a machine for carrying out the present method. As is well known to those familiar with the art, umbrellas or parasols -1 are generally provided with a small colored ornamental tip of celluloid or the like, provided either with a perforation or groove, to which the fabric or umbrella cover is stitched, after which the cover is placed over the frame,

and each tip is attached or slipped over the end of the umbrella rib.

Prior' to my invention, it was necessary to do this entirely by hand, and the machine disclosed in the above entitled patent not only provides a simple and practical apparatus for stitching the fabric tothe tips, but also does it in a neat and finished manner and securely holds the parts in position with the stitches concealed. This latter feature adds to the appearance of the; finished article.

The present invention is directed primarily to a more rapid and convenient method of stitching the fabric or cover to the tips with the stitches substantially concealed, whereby the tips will not only be securely held in place against slipping but will also provide a reinforced finished point of attachment.

A further object is to provide an improved method of the above character which may be ex ditiously and inexpensively carried out.

ther objects will be in art obvious and in part hereinafter pointe out in connection with the accompanying-sheet of drawings illustrating the main steps required in performing a preferred method In this rawing- 1, 2 and 3 illustrate diagrammatically the rst, second and third steps, respectively, of my improved method.

Referring now to the drawing in detail,

the numeral 10 indicates any suitable support adapted to receive for convenience the ornamental tip indicated at .11 while being operated upon. In the present case, this tip is provided with an axial end recess 12 adapted toreceive the support 10 and a central transverse opening 13 thru which a needle, carrying thread 14 is adapted to pass. The tip is suitably clamped in operative position relative to the support 10 by any approved means (not shown).

A portion of the umbrella cover is indicated at 15 and this entire cover, as is well known to those familiar with the art, is usually made up of a plurality of triangular pieces of cloth, one of which is adapted to be positioned between each pair of ribs. These triangular pieces of cloth are stitched together and form a seam 16, which lies adjacent and parallel to one of the umbrella ribs when assembled.

In carrying out the present method, I prefer to mount the ornamental tip 11 on the support 10 with the exposed ornamental end 17 extending outwardly or away from the support 10. The fabric is then laid inside out upon the tip and extending rearwardly of the ornamental end of the tip with the seam 16 adjacent one side and parallel to the longitudinal axis. The fabric is then secured to the tip as by means of the stitching indicated at 14, and as herein shown the threaded needle is passed thru the fabric and opening 13, then to one side, back thru the opening 13, and then to the other side, this operation bein repeated and any number of stitches ta en as appear to be necessary to hold the fabric in itssecured position.

The tip 11 is then removed from its supportlO, as shown in Fi 2, and the operation re ated until all the tips are secured. The fa ric 15 is then turned right-side out or back on itself to the position shown in Fig. 3, thus providing a neat finish about each tip, the stitching 14 bein entirely concealed by the cover 15. The abric is also reinforced at this point against wear by reason of the double thickness of fabric, and the parts are securely held against slipping,

As will be understoo from my prior patent, the clamped tip and the support 10 are movable relatively to a reciprocating needle in successive steps, whereby the reciprocating needle passes thru and about the tip; obviously the tip and support may remain stationary, and the reciprocating needle may be caused to shift its path of reciprocation, thus to secure the fabric to the fixed tip.

While only one of the various types of ornamental tips is herein shown, it is of course to be understood that other available forms may be used, the main idea being that the fabric is secured as by stitching to the tips with its reverse side facing outwardly, and is thereafter turned back on itself from its secured portion and/or portions so that its front side faces relatively outwardly. The tips may then be mounted on the ribs of the umbrella frame with the fabric of the umbrella disposed in secured relation thereto.

It is thus seen that the present invention provides a simple and practical method of making umbrellas, and more particularly to the securing of the umbrella cover or fabric to the ornamental tip.

Without further analysis the foregoing will so fully reveal the gist of this invention that others can by applying current knowledge readily adapt it for various applications without omitting certain features that, from the standpoint of the prior art, fairly constitute essential characteristics of the generic or specific aspects of this invention, and

therefore such adaptations should and are intended to be comprehended within the meaning and range of equivalency of the following claims.

I claim:

1. The herein described method of attaching a fabric cover to an umbrella frame including ribs, each having an end tip, which consists in first placing the cover about the tip with its reverse side facing outwardly, securing the reversed fabric to the tip, then turning the fabric back on itself from its secured portion so that the front side of the fabric faces outwardly, and mounting the tip upon an umbrella rib.

2. The herein described method of attaching a fabric cover to an umbrella frame, which consists in first placing the cover about a rib tip with its reverse side facing outwardly, passing a thread through the fabric and about the tip whereby to secure the fabric to the tip, turning the fabric back on itself from its secured portion so that the front side of the cover faces outwardly, and mounting the ti upon an umbrella rib.

3. T he herein described method of attaching a fabric cover of an umbrella frame providcd with rib tips, each having thread retaining means, which consists in first wrapping the fabric about a tip with its reverse side facing outwardly, passing a thread through the reversed fabric and into the thread retainin means of the tip, whereby to secure the fa ric to the tip, then turning the fabric back on itself from its secured ortion so that the front side of the cover aces outwardly, repeating the operation for each tip, and mounting the tips at the ends of the umbrella ribs 4. The herein described method of attach ing a fabric cover to an umbrella tip having an eye, which consists in wrapping the cover about the tip with its reverse side outward, passing a thread thru the fabric and the eye of the tip and about the fabric at both sides of the tip, then turning the fabric from its stitched position on the tip and mounting the tip upon an umbrella rib.

5. The herein described method of attaching a fabric cover to an umbrella tip having an eye, which consists in wrapping t e fabric inside out about a perforated tip, passing a. series of stitchesthru the fabric and perforated tip and about each side thereof and then turning the fabric right-side out upon the tip.

6. The herein described method of attaching a fabric cover to an umbrella tip, which consists in laying the fabric about a perforated tip with the seam parallel to the axis of the tip, clamping the fabric and tip in such position, and moving the fabric and tip relative to a reciprocating needle whereby the fabric is stitched to the tip by a series of stitches passing thru the perforation as well as to each side of the tip.

7. The herein described method of attaching a fabric cover to an umbrella tip, which consists in wrapping the fabric inside out about a perforated tip with the seam in the fabric substantially parallel to the axis of the tip, holding the fabric and tip in fixed relation to each other while performing a series of stitches thru the perforation of the tip and at one side thereof, then moving the fabric and tip from clamped relation and turning the fabric right-side out with relation to the tip.
